Goodyear F1 non-EMT Tires

[doylede]

Anyone out there running non-EMT F1's on a Coupe or Vert?
Did you have the air pressure sensors removed? What does this do to wheel balance? Where do you get ordinary valve stems?

If you leave the sensors installed, do they still work?

Thanks in advance for any help.

I have Eagle f1's GS-3's on mine and they perform wonderfully. I left the air pressure sensors in there and they work fine as well.

Me too!

Me too!

I just put mine on less than 2000 miles ago. Have you had these for a while and if so how many miles do they last for you? I occasionally like to have fun but I don't really do burnouts and I don't autocross

My tires have been on about two years and have had 10,000 miles or so! I had a little cupping on the inside of the fronts and I got it aligned in the spring!

I hear there is a problem with the F1 GS Steel (non-runflats) and the pressure sensors - something about the steel belting blocking the transmissions from the sensors.
Definitely keep the tire pressure sensors - it's hard to tell when these low profile tires are getting low on air by looking and when the do look low they are really low. That includes the non-runflats - with runflats, you can't tell they are low at all without a gauge.

Tuna,

I'm going with the F1/GS/D3's when it's time for replacements. I have some friends that went with them and all looks good. Quieter than the EMT's and they stick a little better as well. In addition, they just look evil.

I just installed a full set of Michelin Pilot Sport All Season Zero Pressure tires on our 03 last week. Did a little 350 mile road trip over the weekend - rained all weekend too. Quiet, nice ride handled the rain wonderfully and they are run-flats. The total cost for the tires, install and balance was just under $1300.

My wife and I really don't want to chance having a flat an leaving her (or me) stranded somewhere and we didn't want to carry the flat repair kits and pumps either. So, runflats were/are our only option.

I put D3's on my 92 and I really like them but they are not runflats.

Of course any new tire will be quieter than the old, hard F1 GS EMT's including a new set of F1 GS EMT's. The problem with the F1 GS EMTs is that they will get harder and noisier again as they age. I've lived through that twice now and thought I'd try a different tire and see what happens in 2-3 years and 20-30K miles.

I have the GS-D3's and I am very happy with them. Great tire! No problem with sensors.

Hi Tuna!

Theresa and I had a flat at 80mph (plus or minus) coming back from Vettes on the Rockies. Put 60 miles on the flat right rear until we could get that tire fixed in Topeka. I was reading "Hemmings Muscle" magazine while at the Goodyear store and found an article from Hib Halverson on ...... runflats (I think it was the Sept. '04 issue). His opinion, after trying to talk to people from Michelin, Firestone, and Yokohama, was that the hard, noisy F1 EMT was the only tire capable of being repaired. He wrote that all the others mandated replacement - and after much less than 200 miles. That said, I know noise and ride quality are great factors in tire purchases. But we were 5 hours from home. In an hour and a half, the tire was plugged - I looked at it when it was off the wheel (which was hardly touched in the repair) and the sidewalls didn't show any stress. Once on the road, we spent 30 miles on back roads checking it out, and then went back up to cruising speed. we both feel the noise was worth it; the car hardly flinched......

ps.....1-800-runflat - from a land phone - got us the closest dealer for the repair, inside of two minutes.

The Michelin runflats are rated at only 50 miles without air. I'm aware of that. Michelin also says that their tire can be repaired. Haven't tried that yet.

One thing I do carry with me on longer trips is a plugging tool and I know how to use it. So for screws, nails, etc.; all I need is air afterward.
Of course Susan would not be able to use the tool but I'm usually with her on long trips.

I was trying to hold out until GoodYear released the new F1 GS2 EMT in C5 sizes but I just couldn't wait any longer. On the C6, this tire is rated for 100 miles without air. It is quieter and better riding - on the C6 anyway. That was my first choice but they are not available yet.

Part of the decision came down to price and wear ratings. The GY F1 GS EMT were more expensive than the Michelin PS A/S ZP at tirerack.com (to the tune of almost $200 more for the full set) and the Michelins have a tread wear rating of 400 vice 300 for the GY.

One of the other things I've read is that if you stop and let the tires cool down regularly - before they exceed the tempature limits, the runflats can be driven considerable distances more than they are rated. Haven't tried that yet either - hope I don't have to.

That's great Survivor! I understand that the runflats on the C6 are just as reliable but with a somewhat softer sidewall so they are not as noisy or bumpy over some highways. How do I solve the problem of a flat with my D3's one may ask? I have a small 275psi aircooled pump in my storage space of my C5 coupe and a tire plug kit! Not a hard thing for me to work with--later I can put a patch over it and pull the plug if I want. Now what if my wife has a flat? I have a can of fixaflat in the car. Do I care if the sensor will need to be replaced if she has a flat. No, I really won't-I have a spare and can always replace it then send the damaged one off to be repaired. So I am quite happy about the D3s. Great handling tire on dry and wet! It all comes down to what the individual owner is comfortable with.

I love the d3's as well but since i just got mine, has anyone gone through a full set, how many miles?

Gy Eagle F1 Gs-d3

OH YEA / GREAT TIRE

Make sure you use the stick on wheel weights as the new rim flange will not let the tire seat properly with regular weights, which look like crap! See my earlier posts on the GY EAGLE F1 GS-D3' s. Yes, I got rid of my stock run flats at 40,000 miles and yes, I do have "Spare Tire Delete" OEM on my 1996/LT4. The low cahnce of having a flat and a cell phone, helped make my decision! The wheel sensors work fine, just make sure the tire technician knows they are there and he/she is certified on "RUN FLAT" technology/equipment!

I have 18,000 miles on my GSD3's - that's about 17,300 road miles, and 700 miles at the track (a 3-mile, 15-turn road course in Willows, CA called Thunderhill.) They are really sticky, but track days take a toll on these softer tires. After the 2nd day at the track, the outside corners are really showing significant wear; and I expect to have to replace them before I go out again. $900 for new rubber all around is a steep price for 2 days at the track, so I'm looking for any advice on street-legal tires that might hold up better under spirited driving.

For reference, I put 48,000 miles on the original EMTs, which included my first track day. They guys at the tire shop were shocked that I got that many miles out of the original tires; I limit my spirited driving to track days!

The only way to go is Michelin Pilot Sport A/S Z/P. Believe me I know as I tried it and I like it ! Good Luck !
